How To Debug The Thread Cutting Mechanism Of Embroidery Machine

Under the environment of labor shortage and increased production costs, more and more domestic embroidery machines are equipped with automatic shearing mechanism, and the domestic embroidery machine is not stable due to the shearing mechanism. Thread cuts often occur from pinholes after shearing. This is also a problem faced by many maintenance workers. The author maintains his own embroidery machine shearing mechanism. debugging Write out in the heart, for your reference, I hope to help you, if there is a shortage of correction. This paper introduces the adjustment method of pinhole dropping on the rear line of embroidery machine.

　　 1. the adjustment of the electromagnet shear line (shear angle 294 degrees + 2 degrees).

When the spindle is 100 degrees, the electromagnet is lifted into the cam groove. When the hand spindle is scissor, it is observed whether the disc is in the cutting position (294 degrees) when it is fretting. If deviation, loosening the top gear of the chain drive gear on the lower shaft, turn the spindle to (294 degrees), rotate the cam in the clockwise direction, and lock the top wire when the scissors move slightly. Attention: large degree. Shear line The length of the rear thread is long.

　　 2. adjustment of fastener fork

Adjust the fastening screw of the fastener fork B and the black eccentric rubber apron on the gear case, so that the thread fork can touch the shuttles just now. The left and right position of the buckle fork is centered on the hook line of the positioning line of the shuttle shell. Note: when the fastener fork position is lowered, the thread length is longer when the thread is cut. Instead, check the position of the wire electromagnet pallet and adjust it to the position where the electromagnet is absorbed. Turn the color changing motor and connecting rod mechanism with the handle to observe whether the needle position display lamp changes accordingly. If there is no indication, or some position shows that some positions do not show, the needle position detection board fails, and the thread ends are shorter when trimming.

　　 3. adjustment of scissors position

　　 Embroidery machine Check whether the plug-in is complete and re insert in the case of closing the knife. Observe the position of the needle to check whether the half turn indicator light on the board is bright. If it is not bright, measure the DC 12V switching power supply. If there is no output, the tool tip should be leveled with the edge of the fixed knife.
